After a little research on the pinout of the 9 pin RS-232 connector, I have deduced I can't get multiple inputs, such as AFR and RPM without a device, such as an LM-1. So much for cheaping out on that!

Here is where the AFR's were on the dyno, prior to the install of the RPM solenoid switch. Boost for this test was at about 6 PSI, not 7.5 as noted.
And, I will over the weekend check to make sure my blowoff valve is closed down under boost, and not cracking open. I hope the fix is so easy. We had some of that Minn weather here the past few days...
